作为艾滋病毒护理连续体系的第一步，及时诊断是减少病毒传播和结束艾滋病毒流行的关键。研究表明，离考点的距离对于方便获取服务和教育材料至关重要。这项研究展示了如何利用2015-2019年有关宾夕法尼亚州费城艾滋病毒流行率、检测地点位置和与艾滋病毒相关的因素的现有公开数据，使用位置分配分析来改善艾滋病毒检测服务的分配。使用ArcGIS位置分配分析工具计算艾滋病毒检测地点的位置，采用的方法是最大限度地减少需求点位置与服务设施之间的距离。邮政编码水平的需求最初是基于晚期艾滋病毒诊断的百分比，并在基于多种因素组合的敏感性分析中确定的。出行时间和从需求到设施的距离决定了设施的选址分配。这项分析是在2021-2022年间进行的。与位于20个(43%)费城邮政编码的37个设施相比，该模型建议将测试设施重新分配到37个(79%)邮政编码，使用延迟诊断百分比来定义需求。平均而言，这将使到设施的距离减少65%，到设施的旅行时间减少56%。药敏分析结果相似。在费城更广泛地分布艾滋病毒检测服务可能会缩短距离和到达设施的旅行时间，改善检测的可及性，进而增加了解自己状况的人的比例。
As the first step in the HIV care continuum, timely diagnosis is central to reducing transmission of the virus and ending the HIV epidemic. Studies have shown that distance from a testing site is essential for ease of access to services and educational material. This study demonstrates how location-allocation analysis can be used to improve allocation of HIV testing services utilizing existing publicly available data from 2015–2019 on HIV prevalence, testing site location, and factors related to HIV for Philadelphia, Pennsylvania. The ArcGIS Location-Allocation analytic tool was used to calculate locations for HIV testing sites using a method that minimizes the distance between demand point locations and service facilities. ZIP code level demand was initially specified based on percentage of late HIV diagnoses, and in a sensitivity analysis, based on a composite of multiple factors. Travel time and distance from demand to facilities determined the facility location-allocation. This analysis was conducted from 2021–2022. Compared to the 37 facilities located in 20 (43%) Philadelphia ZIP codes, the model proposed re-allocating testing facilities to 37 (79%) ZIP codes using percent late diagnoses to define demand. On average, this would reduce distance to the facilities by 65% and travel time to the facilities by 56%. Results using the sensitivity analysis were similar. A wider distribution of HIV testing services across the city of Philadelphia may reduce distance and travel time to facilities, improve accessibility of testing, and in turn, increase the percentage of people with knowledge of their status.
